No sound out of HiFi Berry DAC + with Volumio2 (2.799)

Guys, thanks for the troubleshooting effort!

From what I see from your logs, we have 2 problems as of now:

  1. Plugins such as equalizer and parametric eq do not get updated with the latest change (sharberger can you confirm the plugins you have installed? )
  2. On some configurations (PI0 with DSI screen, the audio jack is initialized.

I am doing another test build as of now (which adds snd_bcm2835.enable_headphones=1 ) as proposed by Darmur.

NOTE: We cannot remove compat salsa, since this work is required to prepare support for upcoming kernel 5.4

Please test and let us know, important: write also the plugins you have installed. In case you have equalizer and parametric eq, disable and enable them and save their configuration again.
